I started working on my forehand with a ball machine. The high speed videos do not look good especially since I am trying to do the 'current' forehand, new to me. The strokes do not look very consistent from one shot to the next.....I have a list of errors after just one video. By 'current' forehand I mean the semi-Western grip(probably), the unit turn, 'pat the dog on the head', 'turn the door knob', etc., as best described by Rick Macci in On Court with USPTA and in this month's May '12 issue of Tennis magazine. For stroke description see this video and others in the xstf forehand series. http://www.youtube.com/watch?v=_Oc7U5oJ6ps&feature=fvwrel I started getting a little wrist pain on the little finger side that I believe is due to some occasional poor FH stroke motion. I can also feel the pain if I practice swings with just the racket and no ball impacts. First, I'd like to identify and avoid whatever is stressing my wrist. Any thoughts? Next, I would like to know ahead of time other known injuries that are associated with the 'current' forehand. What are they?
